Progress towards Controlling the Emerald Ash Borer with Biological Control

Scientists have made considerable progress towards controlling populations of emerald ash borer by releasing parasitoids throughout the U.S. Three parasitoid species have been widely established and are beginning to show promise in protecting young regenerating ash forests. Studies also demonstrate the utility of combining insecticide treatment to save large, valuable ash trees with release of parasitoids in urban areas. Speaker: Dr. Juli Gould, Entomologist, USDA-APHIS-PPQ
